Rut Abrain Sanchez on her blog Esturirafi defines and identifies legal and volunteer product labels. Among the latter we find ecologic labels, “so manufacturers show us they are abiding by a series of requirements and for the consumer to be able to identify products environmentally more sustainable”.

There are Type I, Semi-type I, Type II and Type III ecolables. Abrain Sanchez mentions the first two of them, the most common:

Semi-type I label. These ecolabels usually belong to social organizations, sectorial associations, groups of manufacturing firms, etc. with the aim of having the most possible products certified under this system, to achieve that most consumers recognize the products.
